BORING APPARATUS.

Specification of Letters Patent.

Patented May 7, 1907.

Application filed February 1, 1906. Serial No. 298,894.

To a whont it may concern:

Be it known that we, JOHN A. B. TOM]?- KINS and SIDNEY R. HARTWELL, citizens of the United States, residing at VVauwatosa and Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Boring Apparatus, of which the following is a specification.

Our invention relates to improvements in boring apparatus with especial reference to that class of apparatus in which the boring operation is to be performed underneath the surface of water or other liquids.

The object of this invention is to provide apparatus in which the boring tool will be adequately supported, and accurately adjusted to the point of use and guided during the boring operation, although the tool itself is beneath the surface of the water out of reach and out of sight of the person in charge.

In the following description reference is had to the accompanying drawings in which,

Figure 1 shows our invention in side elevation as it is applied to the framework of a pier, the beams of which are shown in crosssection. Fig. 2 is a plan view of the same. Fig. 3 is a sectional view drawn on line 9c-9c of Fig. 1, and showing the major section. Fig. 4 is a detail view in side elevation show ing a modified form of construction, the boring apparatus being removed. Fig. 5 is a detail 'view showing the outer end of the upper portion of the frame and a portion of the driving connections supported thereby and locked in position ready for transportation from one point to another. Fig. 6 is a detail sectional view drawn on line yy of Fig. 5 and showing the means for locking the carriage of the boring apparatus.

Like parts are identified by the same reference characters throughout the several views.

A supporting frame is formed of the upright hanger bars A A, upper horizontal track bars B. B., lower horizontal bars C C and the brace bars D and E. This frame is adapted to be connected with the pier by means of hooks E, adjustable vertically along the bars A A, to which they are secured in any desired position of adjustment by means of bolts e. The frame bars are preferably formed of angle iron and the upper bars B. B each have an inwardly extending flange 1),

which forms a track for the working frame. The lower frame bars C. C serve as guides for the lower portion of the working frame.

The working frame comprises a driving shaft F and stay rods G and II connected in the form of a triangle by the connecting members I, J, and K, respectively. The two upper connecting members I and J are provided with laterally extending stud shafts L which carry rollers M adapted to travel on the flanges e of the upper frame bars B B. The lower connecting member K includes a housing N which incloses beveled gears O, which are adapted to transmit the rotary motion of the driving shaft F to the boring shaft 1 The frame bars A A are provided with a sleeve P through which the boring auger passes. The shaft F may be actuated by means of a crank f or by any suitable power connections, and the working frame is moved inwardly toward the pier by manual pressure as the auger enters the framework of the pier. The supporting frame is held against lateral vibration by means of stay rods Q, which are linked to the sides of the frame bars B B, and are provided with hooks g at their inner ends which are ad apted to be driven into the wood of the pier.

I/Vhen it is desired to move the apparatus from one point to another the working frame is moved outwardly to the outer end of the supporting frame until the rollers M on the coupling member I pass the swinging latch R, which drops to the position in which it is shown in Fig. 6 and holds the working frame in a substantially fixed relation to the supporting frame until the latch R is manually released. When in this position the extremity of the auger will be inclosed and protected by the sleeve P. The latch It is support ed by adjustable brackets r from one of the bars B or B, and if desired, one of these latches may be provided on each of the bars B B as illustrated in Fig. 5. The bracketsr are adjusted along the bars B B in accordance with the length of the boring tool. These frame-bars are connected at their outer ends by a cross piece R.

Referring to Fig. 3 it will be observed that the coupling member K is provided with the arms which project laterally from the coup ling member underneath overhanging flanges of the frame bars C 0 thus preventing the working frame from lifting in the supporting frame, while the edges of the over-hanging flanges prevent lateral movement of the working frame at this point to any extent which would interfere with the operation of the auger.

Referring to the construction shown in Fig. 4, it will be observed that the upright frame bars A A are not connected directly to the pier but are hinged to a connecting member S by ordinary hinge joints T and in such case the pier engaginghooks R will of course be secured to the connecting member S by the bolts 6. With this construction the supporting frame may be swung from side to side and secured at any desired angle by means of the stay rods Q, so that angular holes may be bored in the framework of the pier;

While we have shown and described our invention as used for boring holes in piers, it will of course be obvious that the same may be applied in drilling, reaming, etc., it being immaterial what type of tools are employed in connection with the driving apparatus. The term pier, as herein used, is intended to refer to any relatively stationary support, at the side of which the apparatus'may be attached.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is,

1. A device for boring horizontally under water and having means for securing it to a support above the level of the boring line, comprising the combination of a supporting frame provided with an outwardly extending track; means for suspending the frame at one end from a pier; a working frame depending from said track and adapted to travel thereon; a tool connected to the lower portion of the working frame and extending inwardly therefrom; a downwardly extending driving shaft connected with said tool; a guide for the lower portion of the working frame, and an angular brace extending from the inner end portion of the supporting frame outwardly to the track; said track being adapted to support the operator.
